2013 International Solid Freeform Fabrication Symposium
Proceedings for the 2013 International Solid Freeform Fabrication Symposium. For more information about the symposium, please see the Solid Freeform Fabrication website .
The Twenty-Fourth Annual International Solid Freeform Fabrication (SFF) Symposium – An Additive Manufacturing Conference, held at The University of Texas in Austin on August 12-14, 2013, was attended by 219 researchers from 12 countries. The meeting consisted of plenary and parallel technical sessions. Three special topics were organized into single plenary sessions: “Cyber- enabled Manufacturing Systems for AM”, “Qualification, Verification and Certification” and “Micro- and Nano-AM”.
This year’s best oral presentation was entitled, “Lattice Boltzmann Simulations of Multiple Droplet Interactions during Impingement on the Substrate”, authored by Wenchao Zhou, Drew Loney, Andrei G. Fedorov, F. Levent Degertekin and David W. Rosen from the Georgia Institute of Technology. Selection is based on the overall quality of the paper, the presentation and discussion at the meeting, the significance of the work and the manuscript submitted to the proceedings. Selected from 102 oral presentations, the associated manuscript appears on Page 606. The best poster presentation selected from 16 posters was given by Monica Cadena, Alejandro Hinojos, Sara M. Gaytan, David Bentley, Francisco Medina and Ryan Wicker from The University of Texas at El Paso. Titled, “Characterization of 17-4 PH SS Fabricated by Powder Bed Fusion”.
The recipient of the International Outstanding Young Researcher in Freeform and Additive Manufacturing Award was Dr. April Cooke, presently employed by Paramount Industries, a 3D Systems Corporation Company. Dr. David Rosen won the International Freeform and Additive Manufacturing Excellence (FAME) Award. He is a professor at Georgia Institute of Technology.
The editors would like to extend a warm “Thank You” to Rosalie Foster for her detailed handling of the logistics of the meeting, as well as her excellent performance as registrar and problem solver during the meeting. We are grateful to Mr. Lars Jacquemetton for handling the logistics of proceedings manuscript review as well as most other aspects of the proceedings undertaking. We would like to thank the Organizing Committee, the session chairs, the attendees for their enthusiastic participation, and the speakers both for their significant contribution to the meeting and for the relatively prompt delivery of the manuscripts comprising this volume. We look forward to the continued close cooperation of the additive manufacturing community in organizing the Symposium. We also want to thank the Office of Naval Research (N00014-13-1-0420) and the National Science Foundation (CMMI-1331096) for supporting this meeting financially. The meeting was co-organized by The University of Connecticut at Storrs, and the Mechanical Engineering Department and the Lab for Freeform Fabrication under the aegis of the Advanced Manufacturing Center at The University of Texas at Austin.
